Towards human-like spoken dialogue systems

Jens Edlund, Joakim Gustafson, M. Heldner, A. Hjalmarsson
Computer Science
Speech Commun.
1 August 2008

We present an overview of methods that can be used to collect and analyse data on user responses to spoken dialogue system components intended to increase human-likeness, and to evaluate how well the components succeed in reaching that goal. Expand

Developing Multimodal Spoken Dialogue Systems : Empirical Studies of Spoken Human-Computer Interaction

Joakim Gustafson
Computer Science
2002

This thesis presents work done during the last ten years on developing five multimodal spoken dialogue systems, and the empirical user studies that have been conducted with them. Expand

Prosodic adaptation in human-computer interaction

L. Bell, Joakim Gustafson, M. Heldner
Computer Science
2003

State-of-the-art speech recognizers are trained on predominantly normal speech and have difficulties handling either exceedingly slow and hyperarticulated or fast and sloppy speech. Expand

What makes a good speaker? subject ratings, acoustic measurements and perceptual evaluations

E. Strangert, Joakim Gustafson
Computer Science
INTERSPEECH
2008

This paper deals with subjective qualities and acoustic-prosodic features contributing to the impression of a good speaker. Expand

Speech technology on trial: Experiences from the August system

Joakim Gustafson, L. Bell
Computer Science
Nat. Lang. Eng.
1 September 2000

A corpus of more than 10,000 utterances of spontaneous computer- directed speech was collected and empirical linguistic analyses were carried out. Expand

Modality Convergence in a Multimodal Dialogue System

Linda L. Bell, J. Boye, Joakim Gustafson, Mats Wirén
Computer Science
2000

When designing multimodal dialogue systems allowing speech as well as graphical operations, it is important to understand not only how people make use of the different modalities in their utterance ... Expand

Semi-supervised methods for exploring the acoustics of simple productive feedback

Daniel Neiberg, Giampiero Salvi, Joakim Gustafson
Computer Science
Speech Commun.

This paper proposes methods for exploring acoustic correlates to feedback functions. Expand

The august spoken dialogue system

Joakim Gustafson, N. Lindberg, M. Lundeberg
Computer Science
EUROSPEECH
1999

This paper describes the Swedish spoken dialogue system August. This system has been used to collect spontaneous speech data, largely from people with no previous experience of speech technology or… Expand

Head Pose Patterns in Multiparty Human-Robot Team-Building Interactions

Martin Johansson, Gabriel Skantze, Joakim Gustafson
Computer Science
ICSR
27 October 2013

We present a data collection setup for exploring turn-taking in three-party human-robot interaction involving objects competing for attention. Expand

An experimental dialogue system: waxholm

M. Blomberg, R. Carlson, +5 authors L. Neovius
Computer Science
EUROSPEECH
1993

We will give a general overview of the system and describe some of the components in more detail.Recently we have begun to build the basic tools for a generic speech-dialogue system. Expand
